Raws li kev faib tawm txawv ntawm lub sijhawm txhim kho:
Optical modules tau muab faib ua ob hom: PON optical modules thiab tsoos optical modules.
Thaum siv cov khoom siv kho qhov muag ib txwm siv: Cov teeb liab kho qhov muag kis tau tus mob yog point-to-point (P2P: ib qho kev xa mus rau ib qho), cov modules tau siv ua khub (xws li TX13RX15 thiab TX15RX13), thiab siv ib qho khoom siv kho qhov muag lossis ob lub fibers optical rau kis tau tus mob (qhov no tuaj yeem muab faib ua hom duplex lossis simplex).
Optical fiber link poob muaj xws li attenuation, dispersion, fiber kev twb kev txuas insertion poob, thiab lwm yam. Attenuation feem ntau yog vim lub nqus ntawm lub teeb lub zog los ntawm nruab nrab thaum lub sij hawm kis tau tus mob txheej txheem; dispersion yog vim mem tes broading vim qhov sib txawv ntawm kev sib kis ntawm cov optical wavelengths. Cov tsoos module muaj kev sib kis ntev, mus txog 200km; vim tus nqi tseem ceeb, nws yog siv tsawg dua hauv kev nkag mus rau hauv lub network, thiab feem ntau yog siv hauv cov pob txha caj qaum.
Thaum siv PON optical modules, hom kev sib kis ntawm cov teeb liab kho qhov muag yog point-to-multipoint (P2MP: tuaj yeem xa ntau yam los ntawm ODN), thiab cov modules tsis siv ua khub. Optical fiber link poob muaj xws li attenuation, dispersion, zaus division ratio poob, optical fiber txuas insertion poob, thiab lwm yam.; Qhov kev ncua deb yog luv dua li ntawm cov tsoos modules, thiab qhov kev ncua deb tsuas yog 20km; nws yog tsuas yog siv nyob rau hauv kev nkag network.
Cov saum toj no yog cov lus piav qhia ntawm qhov sib txawv ntawm PON optical modules thiab tsoos kho qhov muag modules coj los ntawm Shenzhen HDV photoelectric Technology Co., Ltd.Cov khoom module tsim los ntawm lub tuam txhab npogoptical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, thiab lwm yam. Cov khoom lag luam saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam muaj kev xav thiab kev ua haujlwm tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos kojtiv tauj pebrau txhua yam kev nug.
